BUG#869012: Wrong result with semijoin + materialization + AND in WHERE

Browse Source 
- in make_join_select(), use the correct condition to check whether the current table is a SJM nest (the previous 
  condition used to be correct before, but then sj-materialization temp table creation was moved to happen before
  make_join_select was called)
